After the Chinese scholars pointed out that the epicenter of the epidemic in Wuhan may have nearly 60 per cent of the infection cases were not detected because of mild or asymptomatic symptoms, the Zhejiang government ordered on 30 March 2020 that all asymptomatic infections will be counted and reported within the control requirements of confirmed cases. Some netizens said that the official statistics show that the epidemic statistics are "good-looking" without counting asymptomatic infections into the confirmed cases. This game can no longer be played.

Recently, the hidden danger of asymptomatic infections of COVID-19 in mainland China have not been counted as confirmed cases  has aroused great concern in the public. Medical experts have frequently spoken, asking the CCP authorities to face the problem in pandemic prevention posed by countless of asymptomatic patients in China.

According to Chinese mainland media reports, at a press conference held by the Zhejiang government on March 30, the head of the Zhejiang epidemic prevention agency announced that in view of the hidden dangers in asymptomatic infection, Zhejiang Province will strictly follow the control requirements of confirmed cases for all asymptomatic infections.

According to the new regulations announced by the Zhejiang Province ’s Epidemic Prevention Agency, asymptomatic infections in the province must be immediately admitted to designated hospitals for 14 days of centralized isolation medical observations. Once the observation period expires, two consecutive specimens must be tested for negative nucleic acid. The sampling interval is greater than 24 hours. After asymptomatic infection is removed from the designated hospital, refer to the management requirements for the recovery of confirmed cases, and then transfer to the centralized isolation point for 14 days.

At the same time, Zhejiang Province also stipulates that when all travelers who come to Zhejiang enter and depart from centralized quarantine, laboratory testing is carried out to achieve the purpose of screening asymptomatic infection.

It is understood that the "Global SARS-CoV-2 Infections Caused by COVID-19" issued by the WHO clearly states that "when clinical signs and symptoms are present, those diagnosed with covid in the laboratory are confirmed cases."

However, in order to reduce the number of confirmed cases, the Communist Party of China has classified the cases that were positive for the viral nucleic acid test of the Communist Party into "confirmed cases" and "asymptomatic" since the fourth edition of the "Novel Coronavirus Pneumonia Prevention and Control Plan" was released on 7 February 2020. As a result, all asymptomatic infections were  no longer counted as confirmed cases.


Hong Kong's English-language newspaper South China Morning Post disclosed on 22 March 2020 that official Chinese Communist Party documents that until the end of February show at least 43,000 asymptomatic infections that had been tested positive were found in China. After 14 days of quarantine surveillance, only those who have symptoms during this period will be amended as confirmed cases announced to the public.

A research team from the School of Public Health of Huazhong University of Science and Technology of China published a paper on the medical paper preprint platform medRxiv on 6 March 2020 pointed out that at least 59 per cent of infection cases in Wuhan have not been detected, which may include asymptomatic and mild symptoms.

In a recent interview with mainland China media, the leader of this research team said that his team based on the most conservative model and the latest statistical data, the calculated data is that there may currently be 59 per cent of undetected infection cases in Wuhan, indicating that local governments may greatly underestimate the number of people with asymptomatic infections, and studies have shown that people with asymptomatic or mild symptoms may be highly contagious.

Wu Tangchun also emphasized repeatedly during the interview that for China and the world, the problem of hidden infections is a very important scientific issue in the prevention and control of the epidemic and should be given high attention.

On the day the Zhejiang government announced on 30 March that asymptomatic infections are required to be diagnosed, a report by mainland China media Caixin.com pointed out that recently there have been many cases of transmission caused by asymptomatic infections in China. The public release of statistics on asymptomatic infections in society is likely to trigger a new public panic.

The article said that the current public opinion has two biggest concerns about "asymptomatic infection": First, the domestic data of asymptomatic infection has not been publicly disclosed, and the public cannot know its scale and transmission trend. Will this make people less alert and necessary? Protection, or triggering excessive panic to fuel rumours? Second, because asymptomatic infections are not counted as confirmed cases, will there be any place where concealed or suspected patients are included in the asymptomatic group in order to maintain "clearing"?

In view of this, some commentators have called for "the number of people with asymptomatic infections needs to be made public as soon as possible, and adequate surveys and research should be conducted to increase public awareness and alertness. At the same time, including asymptomatic infections in confirmed statistics is also in line with current international common practice ... "

The article also quoted experts suggesting that considering the large number of pre-infection infections in Wuhan, in order to find out the scale of asymptomatic infections, a retrospective serological screening in Wuhan should be carried out as soon as possible to prevent the epidemic from rebounding after unsealing.

In the end, this report further quoted the counsel of the health commission's expert group Zheng Xueqian, calling on the authorities to increase the relevant functions of the disease control agencies, and to leave a “slit” for the disease control agencies in the announcement of the epidemic information, allowing the disease control agencies to report directly the epidemic situation to the society in emergencies.
